Frequently Asked Questions
What is Class 4 National Insurance for gig workers in 2026?
Class 4 NI is 6% on annual profits between £12,570 and £50,270. Above £50,270 the rate drops to 2%. It replaces Class 2 NI which was abolished in April 2024.
Do gig workers still pay Class 2 NI in 2026?
No. Class 2 National Insurance was abolished from 6 April 2024. Gig workers now only pay Class 4 NI through Self Assessment.
How is Class 4 NI calculated for gig workers?
Calculate your net profit (income minus allowable expenses). Subtract the £12,570 lower profits limit. Multiply the remaining profit (up to £50,270) by 6%.
When do gig workers pay Class 4 NI?
Class 4 NI is paid alongside your Income Tax when you file your Self Assessment return by 31 January 2027. There are no separate NI payment deadlines.
Does Class 4 NI count toward State Pension for gig workers?
Class 4 NI does not directly build State Pension entitlement. However, since Class 2 was abolished, HMRC uses a notional Class 2 credit to protect State Pension rights for self-employed workers with profits above £6,725.
